` To all whom it may concern Y Be it known that I, HENRY A. AHRENS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and taterof Ghio, have invented a certain new and useful Improvement in Cooking-Ranges, of which the following is a full, clear, and exact description. Y

rlhis invention relates-to certain improvements in cooking ranges which have connected with the range proper a hinged leaf carrying a gas burner which, when the leaf is in a horizontal position, maybe used to heat cooking vessels supported upon said leaf. V V

rhe object of the invention is to provide means by which, when said auxiliary gas burners are in use, the products of combustion'therefrom will be conducted into the space within the range below the range top, whereby the heat from said products of combustion will be utilized'to heat a part ofi-the range top, and whereby also said products of gas combustion will be directed into thestove pipe hole of the stove, instead of beine' allowed to escape into the roomyand to accomplish `these results by means which do not impair the eiiiciency of the range proper when the drop leaf is down and out of use. A l

lThe invention consists in the construction and combination of parts shown in the y drawing and hereinafter described and pointed out definitely .in the appended` claims. Y

In the drawing, Figure 1 is a planview partly sectioned of a cookingu'ange having a drop leaf carrying gas burners, embodying the invention.` Fig. 2 is afront view of the same, partly broken away. Fig. 3 is a sectional front elevation. Fig. 4 is a perspective view of the damper carrying ue which is to be attached to the end of the range; and Fig. 5 is a rear view thereof.

Referring to the parts by letters, A represents an ordinary cooking range which may be constructed to burn coal, gas, or any other fuel.

a represents the top of the range; and a1 l a space below the same which is in communication with the stove pipe hole a3. This space is, of course, in open communication with the iire pot a2 of the range, and is the space through which the products of combustion of fuel by the range will flow on its way to the smoke pipe hole, with the result of heating .the stove top above said space.

B represents the drop leaf which is a shallow box-like construction, preferably built up of sheet metal. Within this boxlike drop leaf and in a plane below the top plate Z? thereof, one or more gas burners C of suitable construction are secured. Each burner is provided with a supply pipe c, the end of which extends to the front edge of the leaf B. Gas nozzles d, which are supported by the auxiliary gas supply pipe D, project into the flaring ends of these supply pipes, and are the means for injecting gas thereto. The flow of gas to each nozzle may be controlled by a valve (Z1. The auxiliary gas supply Dto which gas controlled nozzles are attachedhas a hinge connection Z3 with the main gas supply pipe D1. This hinge itself may be of familiar form, such that it serves as a valve which is open for kthe passage of gas when the auxiliary pipe D is in the horizontal position, but is closed to prevent such passage of gas when said auxiliary pipe occupies the down hanging vertical `position indicated by dotted lines in Fig. 3.

Fixed to the under side of the overhanging part of the top plate of the drop leaf are two downwardly extended ears b3. Two curved arms E are fixed to the under side of the overhanging edge of the top plate a of the range. Their ends are connected .by piv oted bolts e with 'ears 3 of said drop leaf. The axis of these pivot bolts should be alined with the axis ofthe hinge which connects the twogas pipes D, D1. Suitable means, as, for example, two brackets F, which are hinged to the end plate at ofthe range may be 'employed to hold the drop leaf in the horizontal operative position, or allow it-to swing down into a vertical position.

So much of theV construction shown in the drawing as is above described is not original with me. My invention resides in the now to be described additions thereto by means of which the desired results are secured.

A hole o5, preferably rectangular` and horizontally elongated, is formed through the end wall at of the range in a plane between'the top plate a and the horizontal plane in which lie the axes of the pivot bolts e. Over this slot or hole a correspondingly shaped outwardly projecting draft flue G is secured. ,In that end of the box-like drop leaf Which is adjacent to the end plate at, When the leaf is in a horizontal position, `a

. slot or o eninO b5 is cut in such osition that it Will register With the openouter end of said draft flue When the drop leaf is in the horizontal position. In fact, the end of said draftffiue Will then project slightlyinto this hole. IVithin this draft flue an automatically closing damper I-I is placed. This is provided at its other edge With integral 5 pivot, studs z, by means of which it is pivotedjto the draft flue in such manner that gravity causesit to close itself. To a projecting end of one pivot stud/z, an arm h1 i is fixed. A stud J is fixed vto the adjacent end of the drop leaf for engagement with this arm h1, and in such position that when the dropv leaf is swinging up to its horizon# tal'position this stud will engage this arm and will swing the damper open.v The productsl of combustion from the vburners in the drop leaf Will pass through 'this open draft flue into,l the space a2 Within the range vbelow the top plate a thereof, and Will, of necessity, impart some of its heat to `the top plate of the stove; and these ,products of leo combustion will escape from this space into the stove pipe through the same hole a8 that, the products of combustion from *theV f 1.
